In short-demand manoeuvring
situations, such as with yachts otherwise
driven by wind, the electric motor makes
perfect senses. The bigger models are
also a great fit with catamarans, what
with all that flat deck space lending itself
to solar charging. Catamaran sales are
hot to trot at the moment and I can see
a future for electric-driven models with
solar recharging for long-distance cruising.
Volvo Ocean Race
But the one to watch in this market is
Volvo. It’s got massive synergies to harness
across its big truck plays. While there are
some significant differences between land
and water, I can’t see why we can’t recover
water-turbine-driven power generation
and solar to feed back into the engine
bank or tank.
The Volvo Ocean Race recently
announced its bold yacht-racing vision for
the next decade and beyond that includes
a long-term ambition to eliminate the
use of fossil fuels on future (they are all
foiling) yachts.
The V060s will use a hydro-generator
for the first time during the 2017-18 race,
but the new vision includes a 60-foot (18.29
metre) foil-assisted One Design ocean
racing monohull designed by France’s
Guillaume Verdier. Think 20-plus knot
average sailing speeds while creating
plenty of reserve stored power for on-board
use, comms and suchlike.
“Achieving zero fossil fuel while
maintaining safety and communication
capacity will take time as the technologies
continue to develop, but the important
thing is to have a clear goal and ambition,”
said Mark Turner, Volvo Ocean Race CEO.
Of course, the wind is free and for
most sailors an engine is referred to as
an auxiliary for good reason. But for the
point-and-shoot pleasure boaters, the
future isn’t so hard to imagine now.
Electric boats are nothing new, they
can be plugged in at marinas, dry stacks or
driveways, and most boaters are content
with a day-long boating experience. Legacy
craft like our 42ft cruiser have decades of
life left in them, but eventually a whole
lot of outmoded boats are going to be
removed from our waterways.
And the sooner they start with those
forlorn mooring minders the better. h
All eight boats in the 2017-18 Volvo Ocean race will feature hydro-units, which can provide
enough power to run the essential onboard systems in the event of mechanical failure. The
hydro-generator is effectively a propeller which you drop over the back of the boat, similar
to a small outboard, which spins around with the water flowing, generating electricity to be
fed back to the batteries on the boat. Tests have shown no noticeable impact on speed
performance in terms of increase of drag.
